Systemdesign 1 gearbox level

In servo unscrewing devices with one gearbox level, several spur wheels are driven by a central pinion shaft RZW. For thedesign of the system by our project engineers the following information (if available) is needed and applied:

Plastic part

Thread diameter and length

Wall thickness and calculated shrinkage

Type of plastic and fi llers

Injection mold

Maximum tool size and tool height

The number, layout and desired distance of the cavities (sketch available?)

Threaded core- and cooling concept

Process

Mold and melt temperature

Unscrewing time and overall cycle time

Cleanliness level (clean zone, clean room, clean room)

The following figure demonstrates the standard setting for the system design with one gearbox level.
